BYG23T: Diotec's Avalanche Rated 1300V Bootstrap Diode

Discover our bootstrap diode BYG23T in SMA package, well suited for high-side floating gate driver circuits. The major challenge here is to select a robust device with respect to high voltage peaks during low side MOSFET or IGBT turn-off, as well as forward surge currents during re-charging of the storage capacitor. High frequency operation is state-of-the-art in these applications.

The BYG23T features an avalanche rating of 5mJ with breakdown voltage of 1350V and a very low reverse recovery time of 75ns. Repetitive peak forward current rating is 3A, and average forward current 1A.

Various half-bridge gate driver circuits are currently available in the market with integrated bootstrap diodes. The total power dissipation of such gate driver IC is the combination of gate driver losses and the internal bootstrap diode losses. The difficulty with this circuit is the operation at higher frequencies and load capacitance applications, where the power losses in the internal bootstrap diode dominates the overall power dissipation.

An external bootstrap diode, even if in parallel with the internal one, can significantly overcome the problem of excessive power losses in the driver IC. A stand-alone operation is of course possible as well.

SBT1045-3G - LED输出整流器的理想选择

Flyer 3G Schottky Consumer

We are pleased to introduce the SBT1045-3G, the upcoming member of our 3rd generation Schottky family. It comes in a TO-220AC power package and features a repetitive peak reverse voltage of 45V with 10A of average forward current rating. It offers lower power losses both in forward and reverse and is dedicated for a high level of efficiency.

Typical applications include output rectification in DC/DC converters and power supplies, polarity protection and free-wheeling diodes. The SBT1045-3G is an excellent option for output rectification in LED drivers.

Here the main parameters of this part under typical application conditions of an output rectifier:

Vf typ 390mV at If = 10A and Tj = 125°C
Ir typ 10mA at Vr = 5V and Tj = 125°C

First samples are available from September; they can be ordered already now at our orderconfirmation.

Flyer 3G Schottky Consumer

Diotec's -3G Schottky Technology encompasses high power handling capability at small package outlines. It offers state-of-the-art performance in the field of Schottky Rectifiers. Reduced forward voltage Vf and low reverse leakage current Ir are two common features of all these new devices.

Lighting is an essential element in our present world. It plays a decisive role in our daily lives, right from low power indoor lighting at home, to mid and high power outdoor lighting, industrial and horticulture lighting systems. Lighting accounts for about 15% of global electricity consumption.

A new era came with the light emitting diodes (LED). They consume little electricity, are long lasting, versatile and contain no toxic substances. LEDs are the future for lighting. Other intelligent technologies such as digital lighting control systems and smart lighting solutions are emerging in the market, further ensuring an increase in efficiency, greater energy savings and thus lower the carbon emissions.

By choosing the best suited semiconductor components in the design, power losses decrease and energy savings can be pushed even further. Hence, the selection of the right components can also boost-up the overall performance.
We at Diotec Semiconductor focus on supplying high quality products like the 3rd generation Schottky diodes. Their features like low to very low Vf and lower leakage currents make them well suited for a variety of lighting applications like LED lamp drivers, lighting controls, polarity protection of automotive lighting systems and many more.

Our actual -3G Schottky portfolio includes rectifier diodes with (very) low forward voltage drop, reverse voltages from 20V to 45V and forward current ratings from 0.5A to 30A. A new flyer shows dedicated Schottky diodes for lighting applications. If you prefer reading a hardcopy, you can order it here.

Main Features of -3G Schottky Technology:

- Very Low Forward Voltage
- Low Reverse Current
- High Power Capability
- High ESD Robustness
- Energy Savings
- Available with AEC-Q101 grading


-3G Schottky devices are also available for Industrial, Consumer, Energy and Mobility Applications. You can download our flyer here on our website.

SK34SMA L217: 为移动设备无线充电使用场景开发的完美输出整流器

3G Schottky Rectifier for wireless charging

Diotec proudly launches one such device: a 3rd generation Schottky device, which offers not only lower (very) forward voltage drop and therefore lower forward losses but also lower leakage currents, which allows higher standby durations.

The new SK34SMA L217 15MQ040N is a SMD Schottky diode where Vf and Ir were perfectly matched towards the customer's needs. Its a bit of a bulky part number but this can be explained as follows.

The challenge in this case was to build an output rectifier for wireless charging of a battery powered device. During stand-by mode, the reverse leakage Ir must be very low in order to avoid too fast discharging of the battery. In charging mode, the forward voltage Vf must be reduced to provide high efficieny and fast charging times.

Here the typical parameters requested for the output rectifier of the wireless charging system:

Vf typ 0.35 V @ 2 A / 125°C
Ir typ 8 µA @ 4 V / 50°C

Based on our flagship in SMA, the 3A/40V SK34SMA-3G, we built the special version L217. Our customer, a leading manufacturer of battery powered consumer devices, confirmed that this customized device outperforms impressively the parameters of the industry standard 15MQ040N.

Over the past decades, there has been a large increase in the usage of consumer electronics in households, which consumes an enormous amount of energy. These electrical appliances consume energy, not only when they are active, but also when they are left on standby mode.

The industry prioritizes in developing energy saving products, not only to help the environment but also to reduce their financial costs. It is a fact that the semiconductor technology and the components are the decisive factor in producing energy efficient products.

For many years, we at Diotec have been developing new technological solutions. We have been delivering many energy efficient components intended for energy savings and high reliability systems.
